脂製密閉容器及びその製造方法に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin closed container having a mouth and a synthetic resin film for sealing the opening of the mouth, and a method for manufacturing the same.

Is used. For example, in a medical container, an infusion solution or the like is injected into the container. In food containers,
Beverage, food, etc. are poured into the container.

をシールしていた。However, since the container manufacturing and the filling of the contents are not always performed at the same place, it is necessary to transport the container. Therefore, in order to maintain the aseptic state during transportation and prevent the entry of foreign matter, or to prevent the deformation of the container during transportation, after filling the container with sterile air,
A synthetic resin film (hereinafter, sometimes referred to as a film) was welded to the surface of the mouth of the container by heat welding to seal the opening.

薄いフィルムにより開口部をシールすることが必要とさ
れる。In consideration of workability at the time of injecting an infusion, it is preferable that the film is thin. For example, if the film is thin, it shrinks due to heating, so that it can be easily opened without peeling. Therefore, it is necessary to seal the opening with a film that is as thin as possible.

った。However, in the method by heat welding, the film itself shrinks, so that the thickness of the film cannot be reduced, and it is difficult to weld the film having a thickness of 30 μm or less. Therefore, if a conventional thick film is shrunk by heating to open it, a large amount of heat is required, so that the mouth portion may be deformed.

った。Although it is possible to weld the film by ultrasonic welding using longitudinal vibration, it is necessary to provide a ridge on the surface of the mouth portion as a welding margin, and it is necessary to change the design of the mouth portion. Further, since large irregularities are generated in the welded portion, when the cap or the like is attached by welding after the contents are poured, the irregularities may cause insufficient welding.

【０００７】本発明の目的は、口元部に薄い合成樹脂フ

にある。An object of the present invention is to provide a synthetic resin container in which a thin synthetic resin film is welded to the mouth portion so that the irregularities of the welded portion are small and the opening is sealed, and a method for producing the same.

る合成樹脂製密閉容器を採用した。As a result of extensive studies to achieve the above object, the present invention has a mouth portion and a synthetic resin film which is welded to the surface of the mouth portion and seals the opening portion of the mouth portion. In the synthetic resin hermetically sealed container, a synthetic resin hermetically sealed container is used in which the welded portion of the synthetic resin film is welded to the surface of the mouth portion by ultrasonic torsional vibration.

易となり、溶着が不十分となることはない。Since the synthetic resin film is welded to the surface of the mouth portion by ultrasonic torsional vibration, the unevenness of the welded portion is smaller than that of ultrasonic longitudinal vibration. As a result, after the contents are poured, the cap or the like is easily welded to the mouth of the container, and the welding is not insufficient.

なるので、内容物注入の作業効率が向上する。In the present invention, the thickness of the synthetic resin film is not limited, but it is preferably 100 μm or less, and 30 μm or less.
The optimum value is m or less. Since the welding is performed by ultrasonic torsional vibration, the heat generated by the welding is local, and the heat does not shrink the film. Therefore, it is possible to seal with a film having a thickness of 30 μm or less, which has been difficult with conventional heat welding. As a result, the film opening operation is facilitated, and the work efficiency of the content injection is improved.
